Answer: A is the right answer


Step-by-step explanation:

y=4x+5

m=-4/-1=4

y-3=-1/4(x-8)

4(y-3)=-x+8

4y-12=-x+8

4y=-x+20

y=-1/4x+5

!!URGENT!!WILL GIVE BRAINLIEST!! GEOMETRY DILATIONS!!! PLEASE INCLUDE EXPLANATION
Sergeu [11.5K]

Unless otherwise specified we usually assume the dilation is about the origin. That is you can tell the scale factor by the way the distance to the origin changes.

Point C, for example, is 6 units from the origin. Its image, C' is 4 units from the origin. Then the scale factor image/original is 4/6 = 2/3.

Your green question mark gets filled with 3 to make the fraction 2/3.

_____

To find the translation, pick any point on A'B'C' and find the corresponding point A'', B'', or C''. Count the squares you have to go left to get from A' to A'', for example. That will be 5 to the left. Similarly, count the squares you have to go down to get from A' to A''. That will be 4 down.

Rates like $ per channel is a slope, "m". The added fee is a constant so it's the intercept "b".
y = mx + b

So for the first problem (9)
(a)
y = total cost in dollars
x = number of premium channels
y = 16x + 44
(b) when x = 3 channels
y = 16(3) + 44
y = 92 $

the second problem (10)
(a) every 4 years the tree grows by 12-9=3 ft
So the unit rate or slope will be 3 ft per 4 yrs, (3/4). You can see this also by solving for slope "m" using the given points (4,9) and (8,12).

x = number of years
y = height of tree in ft
y = (3/4)x + b
use one of the points to find the y-intercept "b".

9 = (3/4)(4) + b
9 = 3 + b
9 - 3 = b
6 = b
y = (3/4)x + 6

(b) when x = 16
y = (3/4)(16) + 6
y = 12 + 6
y = 18 ft

A salesperson receives step commission on sales calculated as follows: * 8% on first $1000 _________________ * 12% next $2000 __
Sonja [21]

Step-by-step explanation: Assuming the commission is calculated on a weekly basis and no sales were made on Saturday or Sunday:

Total Sales = $12794.23

8% of $1000 = $80

12% of $2000 = $240

20% of $9794.23 = $1958.85

Total = $2278.85
